Patented Nov. 11, 1952 UNITED STATESY PATENT FFICE COLLAPSIBLE LINEDTRAY OR CARTON Mich.

This invention relates to improvements in colchinery and which when setup is strong and rigid,

the liner providing a complete unbroken liner for the interior of thetray or carton.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is pointed out in theclaims.

A preferred embodiment of the invention'is illustrated in theaccompanying drawings, in

which Fig. 1 is a perspective View of a tray or carton embodying myinvention completely erected.

Fig. 2 is an enlarged fragmentary perspective view illustrating one ofthe steps in erecting the tray or carton.

Fig. 3 is a similar perspective view illustratin another step in theerecting of the carton.

Fig. 4 is an enlarged fragmentary View in section on a linecorresponding to line 4--4 of Fig. 1.

Fig. 5 is an enlarged fragmentary view on a line corresponding to line5-5 of Fig. l.

Fig. 6 is a fragmentary plan View of one corner of the blank with theliner omitted.

Fig. 7 is a plan View of the blank extended with the liner thereon, onecorner of the liner being turned up to disclose therelation of certainparts.

The embodiment of my invention shown in the accompanying drawingcomprises a bottom I, side Walls 2--2 hingedly connected to the bottomalong the lines 3-3 and walls 4-4 hingedly connected to the bottom alongthe lines 5-5. Corner flaps 6 are hingedly connected to the end wallsalong the lines l. These lines are ordinarily score lines.

The side walls have diagonally disposed slits 8 therein opening at theirend edges thereby providing delectable portions 9 above the slits. Thecorner flaps have slits I0 therein providingV tongues Ii engageablethrough the slits of the side walls. When erected, the lower portions ofthe corner flaps are inserted through the slits 8 and are positioned onthe inner sides of the side walls below the slits thereof. The tongues II engage the upper edges of the slits or the deflectable portions 9 ofthe side walls with upper portions of the corner flaps on the outersides of the deflectable portions 9 of the side walls and in supportingengagement therewith.

These parts and their relationship is substantially that of my Patentber 221949.#

Application February 14, 1949, Serial No. 76,299

5 Claims. (Cl. 229-35) The .liner sheet I2 is of suitable flexible ma--terial desirably of cellophane, Pliofilm or other moisture or greaseresisting material. `This liner sheet is of a dimension substantiallycorresponding to the length and width of the blank when at, the cornersare preferably cut off as indicated at I3. 'I'he liner is adhesivelysecured to the side and end walls by spots of adhesive indicated at I4located near the outer edges of these walls. The liner is alsoadhesively secured to the corner flaps by spots of adhesive indicated atI5.

It will be noted that the liner is not adhered to the tongueportions orthe portions below the tongues or the inner ends of the corner flaps or`to the portions of the side walls above the slits 8 therein. With theliner thus attached to the wall blank the blank may be quickly andeasily set up, the liner not interfering with this operation or theinsertion of the lower ends ofthe corner flaps through the slits 8 orthe engagement of the tongue with the slits.

As the .end walls are verected from the position f shown in Fig. 2 thedeflectable portions of tliff side walls are pressed inwardly somewhatto re-j'.

ceive the corner flaps. As the end walls and cor,- ner flaps are swungto erected position the liner is drawn or wrapped around the end edgesof the side walls and portions thereof disposed between the portions ofthe corner flaps on the outer sides embodied in a square tray or cartonor other shapes. It is a matter of convenience in erecting when the trayor box is elongated to have the slits on the side Walls and the corner`flaps on the :j end walls, that is, considering longer and shorterdimensions.

I have illustrated and described my invention in a highly practicalembodiment thereof. I havenot attempted to illustrate or describe otherernbodiments orvadaptations which I contemplate as'V it is believed thatthis disclosure will enable those skilled in the art to embody or adaptmy invention as may be desired.

Having thus described my invention, whatf''fv claim as new and desire tosecure by Letters Patent is: l 1

. 1. A tray or carton formed of an integral blank comprising a bottomand side and end walls hingedly connected thereto, and corner flaps.-

hingedly connected to the ends of the 'end Walls, the side walls havingslits opening at their 'end edges and extending diagonally outward,`said' corner-'naps having tongues jon theirend 'edges The ends of theside walls abut the4 engageable with the portions of the side wallsabove the slits when the parts are erected, portions of the side wallsabove the slits therein constituting tongue-like members ideflectableinwardly to facilitate insertion of the corner naps and the tonguesthereof through the slitsV and to facilitate the locking engagement ofthe tongues with the side walls with the bottom portions of the cornerflaps Within the side walls and with the upper portions thereof on the'outer sides of the deiiectable portions of the side walls in supportingrelation thereto, and a flexible sheet liner of dimensions approximatelycorresponding to the dimensions of the blank in disposed overlappingrelation to the bottom, side and end Walls and corner flaps, portions ofthe liner intermediate the corner portions thereof being secured to theside and end walls adjacent the outer edges thereof and to the cornerflaps adjacent the hinge connections therefor to the end walls, theportions of the liner overlying the end portions of the side wallshaving the slits therein and the portions of the liner overlying thetongues of the corner flaps being unsecured thereto thereby facilitatingthe interlocking engagement oi the corner flaps and side walls and thefolding of portions of the liner-'around the end edges of the side wallsand between the portions of the corner flaps overlapping the outer sidesof the side Walls, and the holding of the liner tautly against the innersides of the side and end Walls.
